Greetings all,I have a 200 amp DC Inverter Tig welder.  Following a short inside the torch handle at the trigger switch, I have no Tig functionality.  No HF start, No scratch start.  The MMA functions properly.  The fan runs but no activity when torch trigger is activated in Tig mode.  I repaired the trigger in the torch and even tried a new torch to rule that out with no success. The torch side of things seem fine.Any ideas what I should be looking for next? I've looked inside and see no obvious signs of foul play...nothing burned, scorched, melted, oozing, buldging or otherwise...Any ideas and or suggestions would be greatly appreciated.  Thank You.

Reply:Good luck getting it fixed.
Reply:You said there was a short at the trigger switch. How did you attempt to fix it?  The switch is basically just continuity, so the wires were bare and shorted to: each other?  Another metal part? 1st on WeldingWeb to have a scrolling sig!
